Farr 30/30 pleated filters have established a new air filtration
standard in a wide variety of commercial, industrial and residential
applications. High efficiency ratings, extended service life and ease of
handling have made them the accepted choice where both performance and economy
are required.

EXCLUSIVE FILTER MEDIA - Farr 30/30 Class 2
filter media is a lofted, high performance, nonwoven, reinforced cotton and
synthetic fabric. It is specially manufactured by Farr Company to rigid
performance specifications. The media has a minimum thickness of 0.15" and
has a unit weight of 2.5 ounces per square yard. The media is fully supported
and bonded to a welded wire grid with 96% open area.

PERFORMANCE
- Farr 30/30 filters, U.L. Class 2, are rated on ASHRAE Test Standard 52.1-92 at
30% efficiency, arrestance is 90-92%. The 30/30 may be operated at varying
velocities up to 600 fpm for the 4" 30/30 and up to 500 fpm for the 2"
and 1" 30/30 filters.

EASY TO UPGRADE - New or
existing systems can be upgraded by incorporating the Farr 30/30. Its greater
dust-holding capacity not only extends replacement intervals, but, considerably
lengthens the service life of any other secondary filters in the system.
